<p>The elastomeric keyboard (100) incorporating a novel interconnect and back-lighting architecture of the present invention includes a printed circuit board (110, 205) and a novel multi-layer membrane switch (210, 215) matrix interconnect structure. The printed circuit board contains a control circuit for powering and controlling the back-lighting of the elastomeric keyboard. The electrical components which make up the control circuit are mounted on a top side of the printed circuit board. The multi-layer switch matrix (210, 215) interconnect structure contains multiple holes (505, 605) arranged to coincide with the components of said control circuit. The multi-layer switch matrix (210, 215) interconnect structure also contains a number of electrical connectors (530, 625, 630), a number of conductive contacts (515, 615), and a number of electrical nets (620) for electrically connecting the conductive contacts to each other and to the electrical connectors (530, 625, 630).</p> |
